| Abstract |
Ralstonia pickettii K50 (strain K50) is a denitrifying bacterium that produces low levels of N(2)O under aerobic conditions. In this study, we found that co-culturing of strain K50 with Streptomyces griseus significantly enhanced the denitrification activity of strain K50 in an artificial wastewater (AWW) system. Most factors that enhance denitrification activity were in the high molecular weight fraction of the cell-free broth of S. griseus, and were suggested to be extracellular proteases. Further investigation revealed that the cultivation of strain K50 in protease-treated AWW medium fully enhanced denitrification, and that a shortage of amino acids in the medium limited it. Among the 20 standard amino acids tested, only histidine had a significant effect in inducing denitrification by strain K50. Our results indicate that histidine is a novel inducer of bacterial denitrification.
